Title: Masatoshi Okazaki: Innovator in Loudspeaker Technology
Introduction
Masatoshi Okazaki is a prominent inventor based in Ashiya, Japan. He has made significant contributions to the field of loudspeaker technology, holding a total of 6 patents. His innovative work focuses on improving the performance and durability of loudspeakers through advanced materials and manufacturing methods.
Latest Patents
Okazaki's latest patents include a loudspeaker damper, a manufacturing method thereof, and a loudspeaker and electronic device using the same. The loudspeaker damper is designed with flexibility, allowing it to withstand large inputs without cracking. This is achieved through a resin layer on the damper base material that prevents partial interface peeling. The damper material is created by impregnating a substrate with thermosetting resin, which includes a flexibility imparting agent. This innovative approach results in a loudspeaker damper that can handle high input resistance while maintaining its structural integrity.
Another notable patent details the method of manufacturing a damper for a loudspeaker. This process involves molding a substrate into a desired shape using a fabric or knitted cloth made from core-sheath type conjugate fibers. The resin used for the core material acts as a matrix, while the sheath material, which has a lower melting point, is fused during heat treatment. This method simplifies the production process and results in a damper that boasts excellent moldability, waterproofness, and durability.
